After years of screaming at his sister Sonica, Sonicboy has developed an extremely annoying scream that will make anyone stop what they're doing and hold on to their ears. Very doubtful toward Laserboy's leadership, he thinks he should be the commander of the Elite Six. Stubborn yet very loyal, you can count on him to stick to a task and go beyond boundaries to make sure everyone on his team is safe. Sonica and him have a very close relationship; he finds Veggie boy annoying after the vegetarian turned his sonic sword into a giant asparagus, and Laserboy irresponsible.
